Bruce, After running for 45 min. "DarkThought" shows the same behaviour as "Ferret" and switches to 1. Nxe6 in iteration #14. It kept this move over night until completion of iteration #16 with a slightly positive score of +0.25. PV = 1. Nxe6 fxe6 2. Qxe6 a6 3. Bxa6 Bxa6 4. Qxa6 Ra8 5. Qc6 Ra5 ... But again this might still be too optimistic (3 pawns for the knight). > [...] > >I would be happy to be shown a line that has any promise for white.

Starting after 1. Rxe6 fxe6 "DarkThought" suggests 2. Bh6 and feels down with a score of -0.5 after overnight analysis. PV = 2. Bh6 a6 3. Nxe6 axb5 4. Ng7+ Kf8 5. Ne6+ Kf7 6. Nxd8+ Rhxd8 ... >As I said before, I like speculative play, and this might be the best way to >play very strong players, I do not know. > >But I don't think this move gets an "!" or "!!" in an absolute sense, I think >it is "?!", and I don't know if this is properly understood by any of these >programs, including mine. You are absolutely right -- most programs including "DarkThought" seem to over-estimate the attacking chances of White in this position. But anyway, it is such an interesting sacrifice with many chances for Black to go wrong that I do not mind "DarkThought" to play it. Other games are lost in much worse fashion than this position (if lost at all) after the sacrifice ... =Ernst=
